Not gonna tell you what it's like, find that out for yourself. Spoilers are bad, after all. If you have any interesting superflat worlds, feel free to share them here. I don't see a whole lot of superflat love going around, so there is always room for improvement.

If you don't know how to make / use custom superflat worlds, I'll explain it. Upon request.
